SENTRY KEY
The Sentry KeyImmobilizer system prevents unauthor-
ized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses the factory-mated Key Fob with Remote
Keyless Entry (RKE) transmitter and Wireless Ignition
Node (WIN) to prevent unauthorized vehicle operation.
Therefore, only Key Fobs that are programmed to the
vehicle can be used to start and operate the vehicle. The
system will shut the engine off in two seconds if an
invalid Key Fob is used to start the engine.
After turning the ignition switch to the ON/RUN posi-
tion, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the light begins to flash after the bulb check, it indicates that someone used an invalid
Key Fob to start the engine. Either of these conditions will
result in the engine being shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.
CAUTION!
The Sentry Key
Immobilizer system is not compat-
ible with some after-market remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

It also includes diagnostics that will illuminate the instru-
ment cluster Airbag Warning Light if a malfunction is
noted that could affect the airbag system. The diagnostics
also record the nature of the malfunction.
WARNING!
Ignoring the Airbag Warning Light in your instru-
ment panel could mean you won’t have the airbags to
protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
airbag system immediately.
Driver And Passenger Advanced Front Airbag
Inflator Units
The Driver and Passenger Advanced Front Airbag Infla-
tor Units are located in the center of the steering wheel
and the right side of the instrument panel. When theORC detects a collision requiring the Advanced Front
Airbags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the Advanced Front
Airbags. Different airbag inflation rates are possible,
based on the collision type and severity. The steering
wheel hub trim cover and the upper right side of the
instrument panel separate and fold out of the way as the
airbags inflate to their full size. The airbags fully inflate in
about 50 to 70 milliseconds. This is about half of the time
it takes to blink your eyes. The airbags then quickly
deflate while helping to restrain the driver and front
passenger.
The Advanced Front Airbag gas is vented through the
vent holes in the sides of the airbag. In this way, the
airbags do not interfere with your control of the vehicle.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the foot well of
your vehicle. Use only floor mats that leave the pedal
area unobstructed and that are firmly secured so that
they cannot slip out of position and interfere with the
pedals or impair safe operation of your vehicle in other
ways.
98 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show
proper operation of the front and rear turn signal lights.
NOTE:If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective outside
light bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective.
Lane Change Assist
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash
three times then automatically turn off.
Flash-To-Pass
You can signal another vehicle with your headlights by
partially pulling the multifunction lever toward the steer-
ing wheel. This will cause the high beam headlights to
turn on until the lever is released.Multifunction Lever

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Airbag Warning LightThis light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to the ON/RUN position. If the light is
either not on during starting, stays on, or turns
on while driving, then have the system inspected at an
authorized dealer as soon as possible. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
3. Malfunction Indicator Light (MIL) The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in the ON/RUN position before engine start. If the bulb
does not come on when turning the key from OFF to
ON/RUN, have the condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.

12. Position Light Indicator — If EquippedThis indicator will illuminate when the park
lights or headlights are turned on.
13. Seat Belt Reminder Light When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information. 14. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.

the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position. The light should turn off. If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing.
•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to
pass H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
